The most important thing in science is not to be afraid to ask questions.

I would like to fly in space.Absolutely.That would be cool.I used to just do personally risky things， but now I’ve got kids and responsibilities， so I can’t be my own test pilot.That wouldn’t be a good idea.But I definitely want to fly as soon as it’s a sensible thing to do.

真正的领导力在于以诚信做出艰难的决定。

君子的为人之道是：外表暗淡无色而美德日见彰显。小人的为人之道是：外表色彩鲜明，但渐渐地消失了。君子的为人之道还在于：外表素淡而不使人厌恶，简朴而有文采，温和而又有条理，知道远是从近开始的，知道教化别人从自己做起，知道隐微的东西会逐渐显露，这样就进入圣人的美德中了。

We don't have to sacrifice taste for sustainability—we can have both.

Without patience, you cannot learn anything.
